The TDA2549 is a versatile I.F. amplifier and demodulator circuit designed by NXP Semiconductors for use in multistandard television receivers. It is capable of processing both positively and negatively modulated video signals, making it suitable for color and black/white applications.
Key features include a gain-controlled wide-band amplifier for complete I.F. gain, a synchronous demodulator that supports both positive and negative modulation, and a video preamplifier with noise protection for negative modulation. It also offers an auxiliary video input and output with a 75 Ohm impedance, and a video switch to select between the auxiliary input and the demodulated video signal. The device incorporates an A.F.C. circuit with on/off and inverter switches, and an A.G.C. circuit for both positive (mean level) and negative (noise gate) modulation. An A.G.C. output is provided for controlling MOSFET tuners.
This component is supplied in a 24-lead DIL plastic package (SOT101A, SOT101-1). It operates with a typical supply voltage of 12V and a typical supply current of 82mA. The video bandwidth is typically 5.5 MHz.
